Abstract
"MéTODO PARA A SEPARAçãO DE UMA MISTURA DE ALIMENTAçãO E MISTURAS". A invenção refere-se ao campo da separação por destilação de 6-amino capronitrilo (ACN) e hexametileno diamina (HMD) de uma mistura que compreende ACN, HMD, tetraidroazepina (THA), adiponitrilo (ADN) e as substâncias com baixo ponto de ebulição (LB). Também é descrito um método para produção de uma corrente de destilado que compreende HMD; uma corrente de extração lateral que compreende ACN, THA e baixos níveis de dímeros de CN e de HMD; e uma corrente de trás que compreende ACN, THA e níveis substancialmente mais elevados dos dímeros de ACN e de HMD do que aqueles encontrados na corrente de extração lateral. A corrente de extração lateral é particularmente apropriada para ser usada na produção de caprolactama, uma vez que s baixos níves de dímeros de ACN e de HMT não afetam muito a vida do catalisador no processo de produção de caprolactama. A corrente de trás também pode ser destilada para produzir uma corrente de destilado de trás que compreende CAN e THA, que podem ser reciclados novamente à primeira coluna de destilação, aumentando ainda mais a recuperação de CAN da corrente de alimentação. As condições do processo do método da invenção desfavorecem a podução de 2-ciano ciclopentilideno imina (CPI).
